Whistles with a Turbine, STEM Play

SummaryWhistles with a Turbine, STEM PlayThis project is a play on a previous whistle project. What will happen if one adds a turbine, with a varying number of blades, to an existing whistle? Well, it does not sound like a whistle anymore. It still makes some interesting sounds. All in all, it is an interesting design project to show STEM connections.To make a whistle, one needs a body, a turbine, and a snap-on cover. A touch of lubricant to the inside of the turbine may improve spinning. A touch of superglue might be helpful for a permanent assembly.Among the filesThree different bodies: one with a 7mm opening; one with no opening; another one with a curved airway . They all use the same cover.2.Turbines with varying numbers of blades.Two covers, including one that is slightly tighter.Also included is a regular whistle as a reference (5mm opening) with no ball in it.Print SettingsRafts: NoSupports: NoResolution: 0.15-.2mmInfill: 5-20%Whistles with a Turbine, STEM Playby lgbu is licensed under the Creative Commons - Attribution license.
